Figure 6. Determination of the affinity between the CTB-Aβ42 protein and GM1 by GM1–ELISA.

Figure 6

(A) CTB-Aβ42 fused protein derived from silkworm pupae infected with recombinant virus (circles), positive control, CTB standard protein samples (squares) and negative control, silkworm pupae infected with linearized virus(triangles). (B) The three mentioned samples, both boiled and non-boiled, with the same amounts (50 ng CTB/ml) were measured for A492 signal levels. The results are presented as the means ± SE.
